Corrected real errors: several 1.7.x release dates, resource_pack_send version,
config packet ordering, structured-component count (56), PLAYER_LOADED (1.21.4),
entity_sound_effect field order. Confirmed+cited the rest; remaining ~19 items
re-marked UNCONFIRMED (third-party/ViaLegacy/26.2 internals unreachable from refs).
